Dialing and numbering plan issues for the mixed network 31
ATTENTION
Rule 1: All users in a mixed CS 1000/MCS 5100 network must be accessible by
all systems through a digit-based address.
On the MCS 5100 system, each username must have an alias that is all digits,
or each username must be all digits.
Dialing plan issues
The term "dialing plan" is used in a very broad sense in this context. It
includes all the arrangements that determine an exact digit sequence that
the user must dial to access a destination. To access a destination, a user
must know an appropriate access code (for the type of destination being
called) and the unique address of the destination (within a certain address
space).
In most cases, a set of the following access codes may be needed:
• access code for private/UDP numbers (for example, 6)
• access code for public/local numbers (for example, 9 used for the NXX in
North America and for local exchange Special Numbers (SPN) outside
North America)
• access code for public/national numbers (for example, 61)
• access code for public/international numbers (for example, 6011)
No access code is needed for private/CDP numbers.
Special numbers used to access a service (for example, 911 and 411)
are a special case. Depending on which system is providing the special
number service (CS 1000, MCS 5100, or PSTN), the special number can be
accessed as follows:
• without dialing an access code (for example, with an emergency service
the user dials 911)
• with an access code (for example, with the PSTN directory service the
user may be required to dial 9411).
ATTENTION
Rule 2: In a mixed CS 1000/MCS 5100 network, both systems must have the
dialing plan set up in the same manner. MCS 5100 clients in Converged Mode
must share the UDP LOC of the CS 1000 client with which it is converged.
For example, at a certain location, a user must be able to make a call to a UDP
number by dialing the same digit string on a CS 1000 client as on an MCS 5100
client.
